Ringil

But Fingolfin gleamed beneath it as a star; for his mail was overlaid with silver, and his blue shield was set with crystals; and he drew his sword Ringil, that glittered like ice.

–The Silmarillion, The Ruin of Beleriand

Ringil was wielded by Fingolfin, High King of the Ñoldor. Ringil, as it is a sword made by elves, glows in blue when orcs are near. It does not currently have a crafting recipe, but it will be obtainable through questing in the future. Now, however, it can only be obtained via Creative Mode.

The sword was of Ñoldorin make, and was said to glitter like ice by the light of the stars. Fingolfin wielded it to great effect against Morgoth during their duel before the gates of Angband, wounding him seven times. However, he was slain by the Dark Lord, who broke Fingolfin's neck with his foot. With his last breath, Fingolfin hewed Morgoth's foot with Ringil, rendering him lame for the rest of his existence. Ringil's ultimate fate is unknown, it may have been broken by Morgoth's foot, or it could have been stolen, and then experienced a similar fate to Glamdring and Orcrist.

And after, Faenor took up Ringil, and spoke words, saying that they two, Noldo and Sinda, should bear the armor and sword of the fallen king, both to honour his memory, and to strike fear into the heart of the Enemy and his servants, for the wounds that Ringil gave. And Ithilion arose and took the silver armor of Fingolfin, and donned it, save the helm, which he left, and the captain-prince made his way slowly back whence he came; and Faenor bore Ringil away, as a memory and a promise, a burning brand unto the Orcs, flickering with pale flame and chill to those who felt the bitter edge.
